I assumed this was a belt problem. Ordered the belt and followed the excellent screw by screw instructional YouTube provided by PartSelect. In fact, I probably would not have attempted the repair, until I watched the video and was reassured that I could do it. When I got the front panel off, the problem was obvious. There was a dishrag stuck in the blower. Didn't need the belt, but the video was sure worth the price of the part (~$17). Mr. Appliance charges $109 to DIAGNOSE the problem! This was way easier than dealing with them, especially during a pandemic near the holidays.
Repair was easy, but the part does not come with directions. It is pretty self explanatory if you are used to taking things apart and fixing them. Otherwise there are YouTube videos you can pull up. Dryer runs like it is new again though and it was way cheaper than buying a new dryer.
Called LG on the phone and they gave the button presses for diagnostics, which then gave the HST code, saying the Humidity sensor was bad. The part was described as the Humidity sensor module. Actually it's just the wire leads for the sensor which must be electronic and only accessible by disassembling the dryer. There were descriptions about cleaning the wires, perhaps because some people use dryer sheets which cause a buildup on the wires and prevent them from doing their job. I use wool balls and have no buildup on my wires and replacing them did not fix the sensor, because the module accessible inside the dryer is not the moisture sensor, but only the wire leads.
FIRST REMOVED THE LID ON TOP OF DRYER.THEN THE CONTROL PANEL AND THE STEAM TRAY. HAVE TO UNCLIP TWO HARNEST CONNECTORS. REMOVED THE FACE PLATE THAT HOLDS THE DRYER WALLS TOGETHER ALSO REMOVE TO SENSOR HARNESS CLIPS. .REMOVED THE BELT FROM MOTOR. TOOK DRUM OUT . UNCLIPPED MOTOR COLLAR SNAP CLIPS DISCONNECT THE MOTOR HARNESS. INSTALL NE MOTOR AND CONNECT HARNESS INSTALL CLIP . REINSTALL DRUM AND PUT BELT ON. CONNECT HANESSES AND INSTALL FACE PLATE. INSTALL CONTROL PANEL AND THE TOP LID.
To install the repair part took about 5 minutes. It took a couple hours to take apart of put back together. Unfortunately the part I replaced was not the problem. I still have no heat. My own fault for not testing the parts before ordering. It seems there is no ignition of the gas for the hot air flow. I would be grateful for any suggestions. The video was FABULOUS...really step by step, screw by screw. Thanks for that. Barb Swenson
I took the top off, I disattached the front and took the front top of dryer off, taking the front of dryer off, detached the belt and took the drum out, found the wheels took the plastic triangle off and took the wheels off and replaced wheels, then did everything in reverse and no more thumping. just remember to unplug unit before working on it. And also Part Select is a very good site and place to get parts, very fair priced and very professional.
I had ask how to get the top off., it was simple ,take 3 screws off the bottom angle bracket .and slide top back about 2" then lift.then remove the front panels. '
You will need a helper. Dismantle the Dryer: Remove the screws that hold the top cover, front control panel, front door and front panel. Release the V-Belt under the drum. Remove the Drum. Removed and replace the 2 Front roller assemblies - these were completely worn. Replaced the 2 rear rollers (did not replace the rear roller axels as these were more difficult to remove and they were in good shape) and the V-Belt while I had the whole thing open. Use a shop vac and cleaned up the whole unit. It is so nice and quiet now.
dryer had lent fire and didn't have heat in the dry cycLe.
After replacing the wires and the heat thermostat I realze that I needed to replace the thermostat ntc and the thermostat to blower located under door was burnt during fire. I removed front panel,front facing and tumbler to reach thermostat inter wall. It was easy after fixing to other area prior. I thought it was very easy and didn't cosume much time. I'm a women and it was easy to fix.
Not knowing whether it was the pulley, tensioner, or drum roller I had previously pulled the dryer apart and noticed one roller shaft was rusty for some reason. When the part came in (which was quite fast)I disassembled the dryer to the point that I could remove the left rear drum roller. Replaced the roller and reassembled the dryer (to my surprise without any extra screws or parts left). Fairly easy job, just time consuming.
